[Andrew Corneles]"Now looking into the export features and seeing youtube, iCNNwhatever,
It's obvious to me where the resources were spent."

That's kind of a silly argument. All those web export formats are fairly trivial user interface code wrapping H.264 file exporting. That's not "where the resources were spent" because it would have barely required any resources.

My guess is that by far the most time consuming element of this release was the underlying playback/rendering technology, which is, of course, all going to carry over into future releases that add more workflow features.
